My experience is that it's bad for you to reveal yourself, so I've refrained from doing that. As far as I can tell, all that happens is that the perpetrator gets a low esteem of you, but there's no indication anything else happens, so just keeping it vague seems to be better.
One might have hoped that the perpetrator would have seen it as a lesson to be learnt from, but he acts like most criminals, i.e. blames those catching them rather than their own behavior. Thus, he acts in a realistic manner.
